Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a double-sided chamfering tool with a replaceable cutter head. Background Technology

[0002] After machining holes in shaft-type parts and box-type parts, a chamfering tool is needed to chamfer the hole openings. This removes burrs, makes the edges of the parts smoother, and facilitates subsequent assembly operations.

[0003] The existing Chinese patent (authorization announcement number: CN222448311U) mentions a double-sided chamfering cutter that can fix the angle by using two blades connected to the cutter holder by bolts. When the blade is damaged, the blade can be removed and replaced. It is also convenient to replace the cutter head with different angles to meet different chamfering needs.

[0004] In actual installation, existing chamfering cutters mostly use bolts to fix the cutter bar and the drive unit. Although this is simple and easy, when fixing the cutter bar, the operator usually needs to lift the cutter bar with one hand and fix it with the other, which is not very convenient and increases the difficulty of installation and operation time. Utility Model Content

[0005] The purpose of this application is to provide a double-sided chamfering cutter with a replaceable cutter head, in order to solve the problems of inconvenience in operation, increased installation difficulty and operation time.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A double-sided chamfering cutter with a replaceable cutter head includes a mounting base. A connecting rod is slidably connected to the inner side of the mounting base. The connecting rod is fixedly connected to the mounting base by bolts. A cutter bar is fixedly connected to the bottom end of the connecting rod. A cutter holder is fixedly connected to the bottom of the cutter bar. Blades are symmetrically mounted on the inner side of the cutter holder. A locking mechanism is symmetrically arranged on the outer side of the mounting base.

[0008] By adopting the above technical solution, blades with appropriate angles and specifications are selected according to processing requirements and symmetrically installed inside the tool holder. Then, the tool holder is fixed to the bottom of the tool shank, and the tool shank is then fixedly connected to the connecting rod. Finally, the connecting rod is installed inside the mounting base with bolts, thereby completing the installation of the chamfering tool. The locking mechanism reduces the inconvenience of installation.

[0009] Furthermore, the engaging mechanism includes a fixed frame symmetrically fixedly connected to the outside of the mounting base. Both the mounting base and the fixed frame have slots on their inner sides. A spring is fixedly connected to the inner side of the slot, and an abutment block is fixedly connected to the outer side of the spring. When the abutment block moves, it abuts against the connecting rod.

[0010] By adopting the above technical solution, the elastic potential energy of the spring is released, causing the abutment block to reset and abut against the connecting rod to limit its movement, thereby limiting the movement of the connecting rod.

[0011] Furthermore, a drive rod is fixedly connected to the outside of the abutment block, one end of the drive rod passes through the fixed frame and is fixedly connected to a drive handle, and the drive rod is slidably connected to the fixed frame.

[0012] By adopting the above technical solution, the movement of the drive rod can drive the movement of the contact block.

[0013] Furthermore, a metal pad is fixedly connected to the outer side of the contact block, and the outer side of the metal pad is provided with a rough metal surface.

[0014] By adopting the above technical solution, the rough metal surface of the metal pad can increase the friction between the contact block and the connecting rod.

[0015] Furthermore, a locking block is fixedly connected to the outer side of the metal pad, and locking grooves are symmetrically opened on the outer side of the connecting rod, with the locking block engaging with the locking grooves.

[0016] By adopting the above technical solution, the connecting rod can be accurately positioned in the preset position through the positioning effect of the locking block and the locking groove.

[0017] Furthermore, the inner side of the empty groove is symmetrically provided with sliding grooves, and the outer side of the abutting block is symmetrically fixedly connected with sliders, which are slidably connected to the sliding grooves.

[0018] By adopting the above technical solution, the slider and the groove provide a guiding function for the contact block, so that the contact block can maintain the correct movement trajectory when it moves.

[0019] In summary, this application includes at least one of the following beneficial effects;

[0020] 1. In this application, when the connecting rod is pre-fixed, the elastic potential energy of the spring is released, causing the abutment block to reset and abut against and limit the connecting rod, thereby limiting the connecting rod. This reduces the inconvenience for the workers during installation, makes the operation simpler, and enables the pre-fixation of the connecting rod to be completed quickly, thus improving the installation efficiency.

[0021] 2. In this application, when the abutting block abuts the connecting rod, the abutting block drives the engaging block to engage with the engaging groove. Through the positioning effect of the engaging block and the engaging groove, the connecting rod can be accurately placed in the preset position, thereby improving the installation accuracy.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a double-sided chamfering tool with a replaceable blade.

[0029] Reference Figure 1 and Figure 2 A double-sided chamfering cutter with a replaceable cutter head includes a mounting base 1. A connecting rod 2 is slidably connected to the inner side of the mounting base 1. The connecting rod 2 and the mounting base 1 are fixedly connected by bolts 3. A cutter bar 4 is fixedly connected to the bottom end of the connecting rod 2. A cutter holder 5 is fixedly connected to the bottom of the cutter bar 4. Blades 6 are symmetrically installed on the inner side of the cutter holder 5. A locking mechanism is symmetrically arranged on the outer side of the mounting base 1.

[0030] When machining the workpiece, select the appropriate angle and specification of the cutting blade 6 according to the machining requirements, and install it symmetrically inside the tool holder 5. Then, fix the tool holder 5 to the bottom of the tool shank 4, and then fix the tool shank 4 to the connecting rod 2. Finally, install the connecting rod 2 inside the mounting base 1 with bolts 3 to complete the installation of the chamfering tool. When replacing the cutting blade 6, simply remove the damaged cutting blade 6 and replace it with a new cutting blade 6. The locking mechanism reduces the inconvenience of installing the tool shank 4.

[0031] Reference Figure 2 and Figure 3 The engaging mechanism includes a fixed frame 7 that is symmetrically fixedly connected to the outside of the mounting base 1. Both the mounting base 1 and the fixed frame 7 have slots 8 on their inner sides. A spring 9 is fixedly connected to the inner side of the slot 8, and an abutment block 10 is fixedly connected to the outer side of the spring 9. When the abutment block 10 moves, it abuts against the connecting rod 2.

[0032] Among them, a drive rod 11 is fixedly connected to the outside of the contact block 10. One end of the drive rod 11 passes through the fixed frame 7 and is fixedly connected to the drive handle 12. The drive rod 11 is slidably connected to the fixed frame 7.

[0033] In addition, a metal pad 13 is fixedly connected to the outer side of the contact block 10, and the outer side of the metal pad 13 is set with a rough metal surface.

[0034] Furthermore, a locking block 14 is fixedly connected to the outer side of the metal pad 13, and locking grooves 15 are symmetrically opened on the outer side of the connecting rod 2, with the locking block 14 engaging with the locking grooves 15.

[0035] In addition, the inner side of the empty groove 8 is symmetrically provided with a sliding groove 16, and the outer side of the contact block 10 is symmetrically fixedly connected with a slider, which is slidably connected to the sliding groove 16.

[0036] When pre-fixing the connecting rod 2, first pull the drive handle 12 to move the drive rod 11. The movement of the drive rod 11 moves the abutment block 10. As the abutment block 10 moves, it compresses the spring 9, causing the spring 9 to generate elastic potential energy. At this time, the operator puts the connecting rod 2 into the mounting base 1. Then, the operator releases the drive handle 12. Through the release of the elastic potential energy of the spring 9, the abutment block 10 resets and abuts and limits the connecting rod 2, thereby limiting the connection rod 2. This reduces the inconvenience of the operator's installation, makes the operation simpler, and can quickly complete the pre-fixing of the connecting rod 2, improving the installation efficiency.

[0037] When the contact block 10 contacts the connecting rod 2, the rough metal surface of the metal pad 13 increases the friction between the contact block 10 and the connecting rod 2, thereby improving the limiting effect on the connecting rod 2.

[0038] When the contact block 10 contacts the connecting rod 2, the contact block 10 drives the locking block 14 to engage with the locking groove 15. Through the positioning effect of the locking block 14 and the locking groove 15, the connecting rod 2 can be accurately placed in the preset position, thus improving the installation accuracy.

[0039] When the abutment block 10 moves, the slider and the groove 16 provide guidance for the abutment block 10, so that the abutment block 10 can maintain the correct movement trajectory when it moves.

[0040] Working principle: Select the appropriate angle and specification of the blade 6 according to the processing requirements, and install it symmetrically inside the tool holder 5. Then, fix the tool holder 5 to the bottom of the tool bar 4. The tool bar 4 is then fixedly connected to the connecting rod 2. Finally, the connecting rod 2 is installed inside the mounting base 1 by bolts 3, thus completing the installation of the chamfering tool. When replacing the blade 6, simply remove the damaged blade 6 and replace it with a new blade 6. Pull the drive handle 12 to drive the drive rod 11 to move. The movement of the drive rod 11 drives the abutment block 10 to move. While the abutment block 10 is moving, it will compress the spring 9, so that the spring 9 generates elastic potential energy due to compression. At this time, the operator puts the connecting rod 2 into the mounting base 1, and then the operator releases the drive handle 12. Through the release of the elastic potential energy of the spring 9, the abutment block 10 resets and abuts and limits the connecting rod 2.
